Why does my 15 amp GFCI keep tripping?

[rjhale49]

I’m installing a gfci outlet inline with the power that goes to my well pressure switch. The GFCI will be to power the heat tape on the well supply line. The power is a 20 amp breaker. I installed a 15 amp GFCI jumping from the power line to the line plates on the GFCI. I did this to separate the GFCI from continuous power to the pressure switch. The GFCI outlet powers up but when the pressure switch calls for power the GFCI trips. What am I doing wrong?

It sounds like you have an issue with your heat tape. How many watts per foot is your heat tape

The heat tape works fine plugged into an existing 15 amp outlet.
